  • Multiple laser beam processing
    Patent number: 11780027
    Abstract: Described herein is a system for processing a workpiece that includes a plurality of lasers that each produces a laser beam pulse. The system also includes a laser control module that sequences temporal characteristics of the laser beam pulses. Additionally, the system includes a laser beam compensation module that shapes a near field intensity profile of at least one of the laser beam pulses and adjusts a path length of at least one of the laser beam pulses. The system also includes at least one laser beam position element that combines the laser beam pulses to produce a combined laser beam pulse at a surface of the workpiece.
    Type: Grant
    Filed: March 6, 2019
    Date of Patent: October 10, 2023
    Assignee: The Boeing Company
    Inventors: Alan F. Stewart, Anthony J. Kay, Louis K. Zeldin, Andrea Koumvakalis

  • Energy ratio sensor for laser resonator system
    Patent number: 9793678
    Abstract: A device includes a first sensor configured to generate a first output signal corresponding to an energy of a portion of a forward beam transmitted by a mirror of a laser resonator system. The device further includes a second sensor configured to generate a second output signal corresponding to an energy of a portion of a return beam transmitted by the mirror. A ratio of the energy of the portion of the forward beam and the energy of the portion of the return beam corresponds to a measurement of a feedback ratio of the laser resonator system.
